back and forth with your left hand. Notice that you can reset the control by feel a
detent mechanism holds it in its normal center position.
11. The TUNE control (1) is used to tune up the Mini Moog oscillators to the pitch of
the ensemble in which it is being used, or to its A-440 reference tone. Check to see
that switch (C) is on, and notice that, when a key is depressed, the pitch moves up
and down by a few tones as the TUNE control is turned through its range. Make sure
the PITCH wheel is in its center position, and turn on the A-440 switch (Q). Depress
an A key on the keyboard, and adjust the TUNE control so that the two A's are in
tune with each other. Turn off the A-440. The other two oscillators may now be tuned
to Oscillator 1 using their FREQUENCY controls.
12. The GLIDE control (2) regulates the amount of portamento, or glide, heard
between pitches as first one key and then another is depressed. This control is
activated by turning on the GLIDE switch (R). Setting the GLIDE control at various
levels, play a scale or arpeggio, first with the GLIDE switch on, then using the switch
to introduce glide selectively between certain notes only. Notice that the further to the
right control (2) is set, the longer it will take a tone to move from one pitch to the next.
13. Finally, the KEYBOARD itself functions as a controller. It produces a control
signal which varies according to the position of the key struck. If more than one key is
held down, only the lowest one has effect. The control output of the KEYBOARD is
permanently connected to Oscillators 1 and 2. Switch (B) couples it to Oscillator 3.
Switches (K) and (L) couple it to the filter, and are discussed in the modifiers section,
step 8. The KEYBOARD also produces a timing signal each time a key is depressed.
This will be discussed in the modifiers section in connection with filter and loudness
contour controls.
mixer
Audio signals produced by the three oscillators, noise source, and microphone
preamplifier are combined and balanced by the Mixer section's switches and volume
controls. It is this composite signal, the output of the mixer, which is then modified by
the filter and loudness contour controls and appears as the audio output signal of the
Mini Moog.
1. The OSCILLATOR VOLUME controls (12, 13, and 14) are used to regulate the
relative levels of the audio signals produced by the three oscillators. Switches (C),
